Cladding (Rain Screen)
Welsh//Slate offers the most comprehensive range of slate cladding, available in several exquisite colours. Naturally occurring veining and variations in tone add to the beauty of the material.
With its natural qualities, aesthetic appeal and versatile characteristics, slate enhances prestigious projects world-wide, from public buildings and churches to industrial and commercial developments and residential properties of distinction.
Practical Advantages of Slate Cladding
Slate is generally a non-porous material, which is exceptionally uniform and inert. These properties make it extremely resistant to weathering and chemical attack, whilst the negligible water absorption of less than 0.3% protects it from frost damage.
It is exceptionally durable, unaffected by normal extremes of temperature and it retains its colour, even in UV light.
In addition, it is non-combustible and compatible with all other building materials. Slate is easily maintained, making it an economical choice for all building purposes and is readily available in a variety of sizes, colours and textures.
The Potential of Cladding
The range of colours and finishes available from Welsh//Slate gives the designer immense scope for creativity to achieve the desired effect.
External cladding or internal lining can be held by metal fixings, frames or fixed to precast concrete panels. Masonry units, in course heights up to 300mm and to random or specified lengths with pillared or sawn faces, give the modern designer extensive potential for creative expression.
To further assist in the understanding of this beautiful natural material Welsh//Slate offers a range of R.I.B.A. approved Continuous Professional Development seminars.
Recent projects include:-
- Millennium Centre Cardiff
- Menei Centre Bangor
The versatility of Welsh slate ensures a balance of elegance and durability for contemporary and traditional designs alike.
Welsh//Slate produce cladding directly or alternatively supply part finished raw material for other manufacturers to complete and supply.
